When installed, the installers took the soil that came out of the hole and
used it as topsoil.

I'd dig out the area in question a few inches and get rid of that soil,
and
get some fresh loam.


On the other hand, I have grass growing prolifically in some of the worse
soil you ever saw - clay that doesn't drain, hardens like cement and splits
open 1" wide cracks in summer heat. I've never seeded - this is just very
old grass from about 20 years ago that was left to grow to "hay" before I
got there. Brush hogged it down and just keep mowing. If I till a spot and
leave it go a year it will grow right back - same with burning. Can't kill
the damn stuff.

Noticed my septic tank in Pacific Northwest will not grow grass over it.
I
dug out all the overlying dirt to investigate, but other than some
chunky
rocks (not the cause of the bare area, but certainly not helping either)
and
moist dirt directly atop the tank, I am at a loss.

Is it possible that the exhaust from the tank is noxious to the grass?
Seems odd to me b/c I thought plants thrived when exposed to such an
environment.

Thoughts on the cause and suggestions on what to do to get the grass
growing
for once? Any special dirt treatment?
